The interference of coupling waves can be formulated as follows [61], (5.1.18)Itotal=Icore+Iclad+2IcoreIcladcosϕ where the Icore and Iclad are the intensities of core and cladding modes. Φ is the phase angle that occurred traveling of modes through a length L. It can be extracted ...
a method wherein an inlet pipe and an outlet pipe for NG connected to respective heating pipes are protruded from the end plate of an upper can body and a plurality of coupling pipes connected to the coupling pipe of a lower can body are protruded from the bottom of the upper can body....
The sensing layer was characterized by DRIFTS and ESR, which demonstrate the coupling effects of SAC-Ni and adjacent oxygen vacancy on the surface of SnO2 to enhance SO2 uptake and the activation of chemically adsorbed oxygen as well. This efficient monoatomic catalyst provides innovative insight ...
This is primarily evident in the thermal coupling between subsystems, which is designed based on each subsystem’s inherent characteristics. In other words, this paper not only achieves the cascading utilization of energy based on temperature differences but also considers the safety and operational ...
